Hello, We are travelling out of the country in the fall. I am looking to find something that will keep unopened Insulin cold. Not the FRIO!! We have one and we do not like it at all. Plus, I need something that will keep the insulin at a refrigerated temp since it is unopened insulin, that we would be taking with us as extra vials in case of an emergency. Can anyone recommend a good product? I am having a hard time finding something. Thanks for your help!!
